I just had a look at this. The reason that the template project does not work is that a linker flag is missing. I already informed Ronald, I am sure he will update the template soon.

However, here's how you guys can fix it in your existing project.

Open the project info window (mark the topmost node in the Xcodes left panel, and hit the info button), and enter the "build"-tab. Choose "All Configurations". Now find the setting "Other Linker Flags". It should already contain "-ObjC". Add the new flag "-all_load".

Repeat the procedure in the target info window (the target can be found in the left pane of Xcode as well, and has the same name as the project). Don't forget to choose "All configurations" here, too!

For those who are interested, this is necessary because of a bug in Xcode's linker. Here is more information on that topic:
